LED Strobe Illumination GS Vitec Multiled QT/QX 80mm Fanmount

In the "Multiled QT" model from the manufacturer GS Vitec, two 24V fans are connected in series. After these broke down, I have constructed a cover for a single 48V fan here.
So this is a replacement part, or an improvement on the original product.
